Specification of Letters Patent.

Applicationv filed January 22, 1906. Serial No. 297,366.

To all whom "it may concern:

Be it known that we, KARL KonLMANN and GUSTAV Annnnn, citizens of theUnited States, residing at Dane, in the county of' Dane and State ofWisconsin, have invented certain new and useful Improvements inAutomobilelieels, of which the following is a specification.

Our invention relates to improvements in the construction of wheels forvehicles and especially automobile wheels, and the improvenients consistin making an intcrlockiris; 'wheel-rini and tire whereby the latter isheld securely on the rim against lateral dis- 1.5 placement and ionjgitr1 creeping, and at '-'tlusarhe time the tire may be quickly and e: ilyremovedand replaced.

"in the accompanying" r.l.rawing we have s 'own a preferred adaptation?of .our invent'on in the following views Figure 1 is 2; pers ective Viewof the rim of our im 'n'oved whee Fig. 2 is a perspective view oi thetire of our improved wheel, and

Ti 3 is a plan view of the tire.

cferring to the, details ofthe drawing, .A represents a concave con vexWheel rim made of any suitable material. In the concave face of the rimare out a plurality of trans verse rectangular recesses a which arespaced. apart and formed around the entire rim at suchintervals as inpractice may be found to give themost satisfactory results. Theserecesses arc connected with each other by slots a whicharecut throughtheribs between the recesses, shown in Fig. 1. At intervals, holes (L2are bored transversely in the ribs, to receive retaining bolts asindicatcd by dotted lines in Fig. 1. One or more valve openings orformed .tl. pugh the rim..

B represents the tire which in its general construction may be of anyapproved form or material. Our improvements consist in forming on thefare of the tire, which rests upon the rim, a plurality of lugs b whichare adapted to iit snugly in the recesses a when .the tire is in place.The lugs have holes,

formed therethrough in. which retaining wires p I) are strung. Insteadof several short wires b a single wire may be inserted through. the lugsZ) and extend. around the inner pcriphcry of the tire.

When the tire set in the rim, retaining bolts are inserted through theholes (I? in the rim and pass over the wires 0 thus'sccuring the latteragainst outward movement and thereby 1'.-.vcntii'1g the displacement orthrowinr of the tire when in use. If it be desired to remove a tire, i1;is only necessary to remove the retaining bolts, when the tire can beeasily forced over the edgc'oi' the rim or folly. Inasmuch as. ourimprovements )TOVlLlG for holding the urn against slippage in everydirection, clenclior rims arcnot roquired with our invention.

While we have shown many lugs and recesses, it will'be apparci'it thesemay be reduccd in number and size where the strain on the tire isnormal, but in wheels used on -rac-' slo'ts connecting said recesses, atire having a plurality ol lugs formed thereon and adapted" to lit saidroves cs, a retaining band passing through. said lugs and arranged in.said slots and means dctachably connecting said band 4 with said. rim. I

in testimony whereof we a'llix our signatures in presence of twowitnesses.
